Abstract
A disposable absorbent article is provided which includes a substantially liquid-impermeable, stretchable outer cover, a liquid permeable, stretchable top surface, and an absorbent body located between the outer cover and the top surface. The stretchable top surface can further include a first zone and a second zone. The stretchable outer cover can be configured to provide a first level of elongation when subjected to a tensile force of 100 gmf per inch (per 2.54 cm) of width according to the Material Elongation and Deformation Tensile Test set forth herein, while the first zone provides a second level of elongation that is less than the first level of elongation.
Claims47
A disposable absorbent article which defines a front waist section, a rear waist section, an intermediate section which extends between and connects said waist sections, a pair of laterally opposed side edges, a pair of longitudinally opposed waist edges, a longitudinal direction and a lateral direction, said absorbent article comprising:
- a) a substantially liquid-impermeable stretchable outer cover configured to provide a first level of elongation;
- b) a liquid permeable stretchable top surface attached to said stretchable outer cover;
- said stretchable top surface having a first zone that is configured to provide a second level of elongation that is less than said first level of elongation;
- c) at least one containment component attached to said liquid permeable top surface;
- and
- d) an absorbent body located between said stretchable outer cover and said stretchable top surface.
A pant-like, prefastened, disposable absorbent article which defines a front waist section, a rear waist section, an intermediate section which extends between and connects said waist sections, a pair of laterally opposed side edges, a pair of longitudinally opposed waist edges, a longitudinal direction and a lateral direction, said pant-like absorbent article comprising:
- a) a substantially liquid-impermeable stretchable outer cover configured to provide a first level of elongation;
- b) a liquid permeable stretchable top surface attached to said stretchable outer cover;
- said top surface having a first zone that is configured to provide a second level of elongation that is less than said first level of elongation;
- c) at least one containment component attached to said liquid permeable top surface;
- d) an absorbent body located between said stretchable outer cover and said stretchable top surface;
- and
- e) a pair of fasteners refastenably attaching said laterally opposed side edges in said front waist section to said laterally opposed side edges in said rear waist section to provide said pant-like, prefastened absorbent article prior to packaging.
A disposable absorbent article which defines a front waist section, a rear waist section, an intermediate section which extends between and connects said waist sections, a pair of laterally opposed side edges, a pair of longitudinally opposed waist edges, a longitudinal direction and a lateral direction, said absorbent article comprising:
- a) a substantially liquid-impermeable stretchable outer cover configured to provide a first level of elongation;
- b) a liquid permeable stretchable bodyside liner attached to said stretchable outer cover;
- c) a pair of containment flaps attached to said liquid permeable stretchable bodyside liner;
- d) a surge layer attached to said liquid permeable stretchable bodyside liner;
- and
- e) an absorbent body located between said stretchable outer cover and said stretchable bodyside liner;
- wherein said stretchable bodyside liner and said surge layer combine to provide a first zone that is configured to provide a second level of elongation that is less than the first level of elongation.
A disposable absorbent article which defines a front waist section, a rear waist section, an intermediate section which extends between and connects said waist sections, a pair of laterally opposed side edges, a pair of longitudinally opposed waist edges, a longitudinal direction and a lateral direction, said absorbent article comprising:
- a) a substantially liquid-impermeable stretchable outer cover;
- b) a liquid permeable stretchable top surface attached to said stretchable outer cover;
- said stretchable top surface having a first zone and a second zone wherein said first zone provides a level of elongation that is less than the level of elongation provided by the second zone;
- c) at least one containment component attached to said liquid permeable top surface;
- and
- d) an absorbent body located between said stretchable outer cover and said stretchable top surface.
